METALLIC SHEETING AND LOCKIN BAR.

Original application filed April l, 1922, Serial No. 5 l9, 472.l Divided and this application filedl'lune 12,

To all whom it may concern:

Be it known that we, JOHN RAoKnR W'Ess and HENRY GEORGE GRANVILLE BLAKEMonn, subjectsof the King of Great Britain, re-

siding at London, England, haveinventednew and useful Improvements Relating to lldetallicfiheeting and Locking Bars (for which we have filed application No. 8,626 in Great Britain" on March 19,1921), of which the following is a specification.

This invention has reference "to metallic sheeting and locking clutch bars such as are l employed for the erection of temporary or permanent subaqueous retaining walls metallicsheet piling for cofler dams or as members either alone or in conjunctiton with concrete or the like forbridges, buildings and other structures.

In the following specification the naturev of the invention will be described with reference to metallic sheet pilingbut t isto be understood that the invention is applicable to metal sheets and locking clutch bars employed for constructional purposes gen erally.

Amongst the several objects we have in View are to provide an improved system of metallic sheeting and locking clutch bars wherebythe several sheets may be inter locked one withthe other which compared with the weightot metal employed shall be capable of resisting a considerable degreeot lateral thrust from either side when the members are assembled and of resisting bending movements encountered iniapplication to provide an interlock between the in dividnal sheet members which while 'ensur ing an approximately water-tight joint shall permit of considerablefflexibility at the joints so that a wall of piling for example of curved formation and of comparatively small radius may be constructed.

A further object is to provide an interloclr between the sheet piling members which shall prevent jambing at the joints due to imperfect alignment so that subsequent drawing of the piles will be facilitated for it is to be observed that one of the chief advantages of metallic sheet piling is its adapt ability to repeated usage by being pulled and redriven after the work to be done though its temporary application is finished.

With the aforesaid objects in view and such others as may hereinafter appear or are incidental thereto our invention in its broadest aspect may be said to be embodied in a metallicsheet of trough corrugated or substantial S shape section the longitudinal edges of which are provided with an approximately cylindrical and preferably tan-- gentially disposed bead and independent locking bar or clutch member having two approximately cylindrical recesses adapted to receive, the cylindrical beads of adjacentv sheets in such a manner as to permit of limited-rotation of one sheet relatively to an other around a vertical axis passing through the joint and more considerable angular changes by the possibility of threading the clutch members on the pile in the reverse direction to its normal direction.

Accordingto the present invention the metallic sheet is trough or channel shape in cross section and is formed duringthe usual process of rolling withapproximately cylindrical beads upon its longitudinal edges. The locking bar or clutch member whereby adjoining or juxtaposed sheets are connected 1 together is formed from an approximately H shaped bar the upper left hand vertical limb and the lower right hand vertical limb being elongated and these elongated portions bent inwards to form two approximately cylindrical recesses or grooves adapted to receive the beaded edges of the piling members The mouths of the recesses are smaller than the diameter of the cylindrical beads on the edges of the sheets but wider than the thickness of the metal sheet so that while the metal sheets when engaged with the clutch member will be securely interlocked therewith yet the sheets will be permitted to adjust their alignment with that of the clutch member through a certain amount of The months are formed on opposite sides of the clutch member in such a manner that the two centrelines drawn through the centres of the cy lindrical recesses and passing through the mouths parallel to the edges of the trough shaped metal sheets threaded into the clutch member in the normal manner will be parallel also to each other.

In order that the invention may be clearly understood reference will now be made to the accompanying drawing wherein a preferred construction is illustrated by way of examp\ In the construction illustrated a. are metallic sheets which may be of a trough or channel shape in cross section and are provided with beads bupon the longitudinal edges thereof. The beads Z; are of approximately cylindrical formation and are tangentially disposed and are preferably formed during the usual process of rolling.

To connect adjoining or juxtaposed sheets we employ a locking bar or clutch member 0 formed from an approximately tishaped bar. The upper left hand vertical limb d and the lower right hand vertical limb e are elongated and bent inwards to form two substantially cylindrical recesses to receive the beaded edges of the sheets a, the recesses being formed on opposite sides of the clutch member 6.

With the clutch member constructed in this manner certain advantages may be obtained in the assembling of a wall of piling as it enables the trough shape sections to be arranged with the bottoms of alternate piles on opposite sides of a line passing through the joints while partial rotation around a vertical axis passing through the joints is permitted in both directions.

Meta]. sheets or piling members of trough corrugated or approximately 8 shape in section may be employed under this invention and considerable angular changes in direction of the wall of piling may be obtained by means of the combined flexibility of the joint and the feasibility of threading the clutch member on the pile in the reverse di rection so that specially bent piles for corner work are dispensed with.

Referring to the drawing it will be seen that the pile in the lower recess of the clutch member 0 is threaded in the normal manner but that in the upper recess is threaded in the reverse to the normal. A considerable angular change of alignment is thus obtained.

What we claim is 1. Metallic sheeting and locking bars comprising a metallic sheet the longitudinal edges of which are provided with an approximately cylindrical bead and an independent locking member formed from an approximately H shaped bar the upper left hand vertical limb and the lower right hand vertical limb being elongated and bent inwards to form two similar approximately cylindrical recesses adapted to receive the cylindrical beads of adjacent sheets in such a manner as to permit of limited rotation of one sheet relatively to another around a vertical axis passing through the joint and more considerable angular changes by the possibility of threading the clutch members on the pile in the reverse direction to its normal direction.

2. Metallic sheeting and locking bars comprising a metallic sheet an approximately cylindrical head on the longitudinal edges of the sheet and on opposite sides thereof, and a clutch member formed from an apprmzimately li shaped bar the upper left hand vertical limb and the lower right hand vertical limb being elongated and bent inwards to form approximately cylindrical recesses.

3. Metallic sheeting and locking bars comprising a metallic sheet the longitudinal edges of which are provided with an approximately cylindrical bead and an ind pendent locking member formed from an approximately H shaped bar the upper left hand vertical limb and the lower right hand vertical limb being elongated and bent inuirds to form two similar approximately cylindrical recesses adapted to receive the cylindrical beads the mouths of the recesses being smaller than the diameter of the cylindrical heads but wider than the thickness of the metallic sheet so that the metal sheets when engaged with the clutch member will be securely interlocked in position and will be capable of angular displacement.
